It looks bad, as far as a paint chip goes. Find a close color match & touch it up.

First one?

First one’s always the hardest.
It’s not so bad. Looks like an easy fix, at least. Just make sure you bring the bike in with you when you get the touch-up paint.
I have a bunch of close but not close enough thingies of paint from when I didn’t do that. Like three shades of red and two each of blue and black.

That injury looks like a hole in the Carbon, not a chip. Is it a carbon frame?

That's carbon right, my old eyes can't tell how deep is the ding? If deep, rather than paint I would fill any missing carbon and epoxy with epoxy. Then rough it up with fine sandpaper like a 400 or so grit dot glued to a pencil eraser and then dab some paint until it fills in and then I have had luck with Meguiars Ultimate Compound to smooth it out. I then am careful to keep it waxed.

Difficult to tell from the picture if only the layers of paint are affected, or if the carbon is damaged too.

If its the first case, its structurally non important in my opinion. I would paint it (and I'd probably do a crappy job at it) to protect the carbon from the UV though.

If the carbon is affected, I'm not sure I'd trust it being a fork. I think I'll have it checked by someone competent (no idea who is though). Forks are a part where you don't want to take risks. A fork breaking while riding has too much potential for serious injuries or death IMHO.

I thought that was a clean chip out of the paint. If the ding extends into the fork and is structural, it would probably be best to have that looked at by someone with knowledge of such. Better to play it safe.

And this is why you take it to someone competent for a hands on evaluation rather than on the interwebz.

I agree with this, but there also seems to be a lot of hypocarbondria going around. I've never chipped a carbon fork like this, but most of me wants to believe it's fine. One thing I know 💯 is that if I email the manufacturer or take it to the shop they will say that it will need to be replaced.

CF repair in Tucson. Home - Carbon Fix You might want to offer them $10-20?? for their professional opinion if you want to try the touch up yourself and get some assurance that it's not an unsafe fork. It looks like just a paint chip to me but without seeing and feeling it in the flesh I would advise you not to take my advice.

Agree with those above who say the down side exceeds the upside. Chip seems to have impacted the carbon, which is "notch-sensitive", and can break precipitously. Have evaluated by an expert (Craig Calafee or equivalent) or don't use.

Is the paint chipped as you posted or is the carbon damaged?

I don't know anything about carbon fiber. I really don't think the carbon is damaged.

But it seems like live chipped through a few "layers". Here is a picture with a flash from an angle. It casts a little bit of a shadow so the layers are exaggerated. I sent these pictures to All City and they said "Meh, probably fine. Take it to a shop."

If carbon layers, that would make one uneasy, if just resin or fillers, not so much. I have repainted a few carbon fiber bikes, it might surprise some people how much filler there can be below the original paint.
A magnifying glass can give an up-close look at the exposed fibers. They should be under resin, Worst case, as suggested take it to a shop.

That carbon repair guy just picked it up. His quote was cheap. Better safe than sorry.

What hit the fork to cause that? Forks are pretty stout, but that looks like it was a relatively concentrated force. Id be more concerned about the fork than the paint initially.

A rock. All City said it was cosmetic. The carbon repair guy is fixing it for me now. I'll post after photos when he gives it back.

Whoa. Ok. I just got it back from the repair. He delivered the bike to me and the fork was completely covered in red spray paint. It was, like, a really close match to the color but he totally messed up the fade. It was red almost all the way up to the crown of and down the drop out. It was also a matte finish and totally obviously repainted. Overspray was all over the brake caliper. I thanked him and I ran inside to get some acetone. All the spray paint came off immediately. This was underneath. I dunno if he filled the chip or just sanded it out. It's totally flush now, so, I dunno. I am just going to go get some red paint from the auto parts store and cover that little spot. Bad experience. At least it was a cheap mistake.

The crappy paint would make me want a refund. Can't comment on the chip fix since it's hard to see but not a quality shop IMO. How much did they charge you?
